Biogas is a byproduct of anaerobic digestion and is released during the decomposition of organic materials. It is composed of primarily of methane and carbon dioxide, as well as other trace components including hydrogen sulfide, water vapor, ammonia, oxygen, nitrogen and hydrogen. BIOFerm™ biogas also maintains the lowest possible levels of hydrogen sulfide through a patented removal process. Hydrogen sulfide is a toxic and extremely corrosive substance that deteriorates mechanical components of engines and motors, therefore reducing the efficiency of the CHP or boiler. By retaining low minimal hydrogen sulfide levels, BIOFerm™ biogas ensures the highest levels of biogas utilization efficiency as well as safety for the environment.

The methane content of biogas is directly linked to its quality; the higher the methane content, the higher burning power the biogas has. BIOFerm™ biogas provides the highest levels of methane possible by optimizing combinations of different organic waste inputs. Although exact composition is dependent on the biomass input, the typical makeup of biogas generated from the BIOFerm™ process is 55-65% methane and 35-45% carbon dioxide. BIOFerm™’s specialized hydrogen sulfide removal process results in extremely low hydrogen sulfide content of the biogas, typically less than 200 ppm. This level is safe for generators, CHPs and boilers.

BIOFerm™ biogas can be used in many energy generation applications, including: electric and thermal power production through a combined heat and power unit (CHP), heat generation through boiler technology, natural gas substitution and fossil fuel replacement for vehicle and fleet operation.
